I have a Perry pump (v30) that I plan to test with a smaller engine.
My understanding, based only on anecdotal reports found on the net, is that the Cline regular depends on carb suction to open the regulator and draw fuel from the pressurized tank. I'd like to hear more about the Cline as well.
The Perry is an actual pump (no pressurized tank), but the output pressure is regulated. Perry claims it delivers "an ideal .25 psi" (
http://www.perrypumps.com/prod02.htm). I think it would be an interesting excercise to actually verify that, and hope to do so over the winter.
I can't recommend one over the other... since I have yet to use either! My only conclusion is that it is hard to find concrete information about them.
Here is one person's experience with the Cline:

Here's a guy that couldn't get either to work well:
